L'aranya vespa (Argiope bruennichi) és una aranya que es troba distribuïda per tot el centre d'Europa, nord d'Europa, nord d'Àfrica i parts d'Àsia. Igual que molts altres membres del gènere Argiope, mostra marques grogues i negres a l'abdomen.L'aranya construeix una teranyina orbe espiral de bon matí o al vespre, normalment en herba llarga una mica per sobre el nivell del terra, i tarda aproximadament una hora. La forma de ziga-zaga prominent anomenada stabilimentum, o decoració de la teranyina, que apareix al centre de l'esfera és de funció incerta, encara que pot ser per atreure insectes.
Quan una presa és atrapada per primera vegada a la teranyina, la immobilitza ràpidament embolicant-la amb seda. llavors pica la presa i se li aplica un verí paralitzador i un enzim de proteïna de dissolució.
El mascle de l'espècie és més petit que la femella. Sovint es pot veure a prop d'una teranyina d'una femella un mascle esperant que completi la seva muda final, moment en el qual s'arriba a la maduresa sexual. En aquest moment la seva mandíbula serà suau durant un temps curt i el mascle pot aparellar-se amb la femella sense el perill de ser menjat.
Aquesta espècie d'aranya va aparèixer en la pel·lícula Arac Attack (Eight Legged Freaks).

Scytodes globula, the Chilean tiger spider, is a predatory spider of the family Scytodidae. In Spanish, it is known as araña tigre, or "tiger spider", but is also well known as "long-legged spider" (because of the disproportional size of those members) or "spitting spider" (because of its hunting methods, in which it projects an extremely sticky web which immobilizes its prey). It has achieved fame by being the only natural predator of the extremely common and dangerous Chilean recluse spider (Loxosceles laeta).Description and habitat
The Chilean tiger spider's size varies from 30 up to 70 mm in the adult state. Its body is small (specially if compared to the size of its legs, which are usually between three and four times the size of its body). It has slow movements and it hunts only at night.
The spider is native to South America (it is more common in Chile, but can be found in other parts of South America, specifically in Argentina, Uruguay and Bolivia). It lives mostly inside houses in dark and hidden places such as behind frames, in closets, etc. But it can also be frequently found outdoors under Eucalyptus trees.Hunting method
The hunting method of the Chilean tiger spider is quite characteristic and it is the origin of one of its nicknames, the spitting spider. At night, the spider stealthily approaches its prey and then contracts its abdomen projecting an extremely sticky and resistant spider-web, which imprisons its prey even if it is larger than the spider; then, once the prey is verified to be immobilized, the spider injects its poison, secreted from its second venom gland.
Prey
The Chilean tiger spider preys on flies, mosquitoes, bees, horse-flies, and other insects. However it also eats other kinds of spiders, and it has become famous for being the only natural predator of the common and dangerous recluse spider (Loxosceles laeta).
Webs
The Chilean tiger spider builds barely elaborated spider-webs and only in its refuges.
